NCT00145847
The primary purpose of this study is to determine whether naltrexone is effective in the treatment of alcohol dependence and abuse in patients with schizophrenia and schizoaffective disorder. Hypotheses are as follows: hypothesis 1: Naltrexone will be more effective than placebo in reducing alcohol use. hypothesis 2: Patients responding to naltrexone by reducing alcohol use will also show reductions in severity of psychiatric symptoms and utilization of inpatient and emergency psychiatric services. hypothesis 3: Severity of psychiatric symptoms and amount of service utilization will correlate positively with alcohol use.
NCT00034892
The purpose of this study is to compare the effectiveness, tolerability, and efficacy of the currently available atypical antipsychotic drugs olanzapine (2.5-20 mg/day), quetiapine (100-800 mg/day) and risperidone (0.5-4 mg/day) in patients with schizophrenia, schizophreniform disorder, or schizoaffective disorder who are experiencing their first psychotic episode.
NCT00206128
The purpose of this study is to determine that the efficacy of the sustained release (SR) formulation of quetiapine (Seroquel) is not inferior to the immediate release (IR) formulation. PLEASE NOTE: Seroquel SR and Seroquel XR refer to the same formulation. The SR designation was changed to XR after consultation with FDA.
NCT00214578
The purpose of this study is to determine whether six months treatment with the antipsychotic medicine Seroquel (quetiapine) may affect the schizophrenic patient's glucose metabolism
NCT00234377
The purpose of this study is to document the clinical benefit of quetiapine (Seroquel) sustained release (SR) after switching from another ongoing antipsychotic treatment, regardless of the reason for the switch. PLEASE NOTE: Seroquel SR and Seroquel XR refer to the same formulation. The SR designation was changed to XR after consultation with FDA.
NCT01534936
This is a noninterventional observational study lead amongst psychiatrists, to assess the the overall status of schizophrenic outpatients with affective symptoms treated with atypical antipsychotics.
NCT00736710
Patients with schizophrenia have high rates of cigarette smoking and tobacco dependence, and great difficulties in quitting smoking. The development of novel and more effective treatments for tobacco dependence in this population is thus needed. This study will test the hypothesis that repetitive transcranial magnetic stimulation (rTMS) may facilitate smoking cessation with the transdermal nicotine patch (TNP) in patients with schizophrenia motivated to quit smoking. A total of N=40 smokers with schizophrenia would be assigned to either active rTMS (N=20) or sham rTMS (N=20) as a treatment regimen of 5X/week treatments for four weeks. All subjects would receive TNP (21 mg/24h) and weekly group behavioral therapy for smoking cessation for a total of 10 weeks. The investigators predict that active rTMS will be well-tolerated and superior to sham rTMS for enhancing smoking cessation rates in smokers with schizophrenia.
NCT01491412
This is an observational study describing the real-life antipsychotic treatment during the hospitalisation of the patients due to acute psychotic episode. In this NIS subject's data will be collected at one visit at the moment of discharge from the hospital. The results of the study would help to characterise the discrepancy between current clinical practice and treatment guidelines, indicating that atypical antipsychotics are preferable and should be used in monotherapy during acute psychotic episodes in subjects with schizophrenia. Available evidence have revealed a frequent use of first-generation antipsychotics, polypharmacy, intramuscular route of administration and use of atypical antipsychotics in doses lower than recommended in registered summary of product characteristics.
NCT00734435
The purpose of this study is to determine if zonisamide SR will prevent weight gain in schizophrenic subjects who take olanzapine (Zyprexa)
NCT00538642
Having a diagnosis of schizophrenia or bipolar disorder and being treated with certain of the newer antipsychotics are risk factors for development of diabetes. Subjects with these risk factors plus obesity and/or family history of diabetes who agree to study participation will undergo an oral glucose tolerance test. If the oral glucose tolerance test demonstrates that the subject is pre-diabetic (elevated glucose levels, but below the diabetic range), he/she will have his/her insulin resistance level measured, prior to random assignment to either stay on current antipsychotic medication or switch to ziprasidone. Insulin resistance will be measured again after four months. The primary hypothesis is that insulin resistance will decrease in those switched to ziprasidone relative to those continuing on their same antipsychotic medication.
NCT01714011
Introduction: Schizophrenia is a serious mental illness. For majority of patients it is a lifetime condition,characterized by intermittent episodes of hospitalization due to relapse or acute symptom exacerbation. The nature and course of the disorder impose significant social and economic burden. Relapse is costly, with hospitalization accounting for a substantial portion of healthcare expenses. Second generation antipsychotic side effect such as metabolic syndrome and diabetes mellitus will contribute additional costs to the treatment. Many studies have since then provided convincing evidence for a high risk of diabetes and other glucose abnormalities, metabolic syndrome and mortality due to elevated cardiovascular risk in patients with schizophrenia. However many studies has shown the effectiveness and safety of aripiprazole and ziprazidone.In one of the study, aripiprazole showed improvement of negative schizophrenic symptoms by 25% and 50% of functioning level from baseline. In term of safety, antipsychotics considered to have a safer metabolic profile were amisulpride, ziprasidone and aripiprazole. Study objectives: * To investigate the safety and efficacy of ziprazidone versus aripiprazole in the treatment of schizophrenia patients with metabolic syndrome and diabetes mellitus. * To investigate the reversibility of metabolic syndrome and diabetes parameters following the treatment with ziprazidone versus aripiprazole. Hypotheses: \* The proportion of reversibility of metabolic syndrome and diabetes parameters is higher following the treatment of ziprazidone than aripiprazole.
NCT01050582
The purpose of this study is to evaluate the effects of risperidone compared with other atypical antipsychotic drugs on the physical maturity, growth and development of children, and the risk of prolactin-related adverse events (side effects) associated to these drugs.
NCT00392743
A direct comparison of Positron Emission Tomography (PET) (11C-Raclopride) and Single Photon Emission Computed Tomography (SPECT) (123I-IBZM) D2 RO measurements would allow GSK to gain understanding on the SPECT results obtained with SB773812, and to accurately interpret future D2 RO results from either PET or SPECT studies with new compounds.
NCT01284959
The main objective of this study was to assess subjective experiences related to secondary negative symptoms and cognitive performance in healthy volunteers in response to multiple doses of paliperidone ER and risperidone in a double-blind, placebo-controlled trial. Adverse events caused by these drugs were also evaluated.
NCT01606228
The purpose of this study is to explore the tolerability, safety and efficacy of flexibly dosed paliperidone extended release (ER) among patients with schizophrenia.
NCT01561898
The purpose of this study is to assess the safety of JNS007ER 3-12 mg once daily in patients with schizophrenia over a long term period.
NCT00845572
This study will establish a bi-weekly Consta Club. Participants will begin taking Risperdal Consta after being recommended by their treating physician. As a part of the Consta Club attendees will receive their injection of Risperdal Consta and be educated about important mental health issues. Interviews with study participants will be completed every three months to determine the effectiveness of the change to Risperdal Consta and the bi-weekly group. The overall hypothesis is that the individuals in Consta Club will have a decrease in walk-in visits, emergency procedures and hospitalizations. It is also believed that individuals in Consta Club will have fewer symptoms and better levels of functioning.
